This crank-shaft 0 is retained in the angles, the brace continues downward along head A by the nut a and the washer b, and the side of the crank-shaft to near the point 50 is so mounted therein as to revolve freely, where it again turns and ext-ends a short dis- I00 tance toward the soldering-head, and this short arm is also provided with an aperture through which the shaft passes. In these apertures in the brace the shaft works freely. The soldering-head F is composed of the outside shell I, the spool m, and the detachable point a. Around the spool is wound a coil of conducting-wire in layers, having a layer of mica or other insulating material between each layer of wire. The point 01 is provided with the stem, which is held in place with the set-screw q, as shown in the modification shown in Fig. 8. The point can also be arranged as shown in Fig. 7, with a screwthread cut on the stem and screwed into the crankshaft, and washers are used as required to make a close connection, and the length of the retaining-point can thus be adjusted.

The operation of the invention thus described will be readily understood from the accompanying drawings, and may be briefly described as follows: The conducting-wire having been connected with a main current of electricity, the soldering-point soon becomes heated and ready for use. The point of the crank-shaft is made to rest in a dent in center of the can-cap and the soldering head pushed down, as appearsin Fig. 1, and by turning the handle the soldering-head is made to rotate around the shaft-point, which should be adjusted to the proper distance from the crank-shaft. As soon as a completed circle has been described with the soldering-head it is again raised and appears as in Fig. 4.

\Ve do not Wish to be understood as confining ourselves to the exact form of construction and arrangements of parts as herein shown, but hold that minor changes may be made therein and still be within the scope of our invention.

Having fully described our invention, what we claim is 1. In an electric soldering-iron, the combination with the crank-shaft having a swiveled head at its upper end, and pointed at its lower end, so as to center in the top of a can. of a contact-maker connected to said head by suitable tubes, conducting-wires leading 3 through said tubes, to suitable contact-making devices, a tube extending from an arm secured to the contact-maker, downward, a brace secured to the lower end of said tube. adapted to carry a solderingtool having an electrical heating resistance-coil and elec trical connections extending from said con tact-maker to the heating-coil, substantially as specified.

2. The combination in an electric solderingiron, of the crank-shaft, the contact-maker and conducting-wires, and the handle sur rounding the bend of the crank-shaft and the tube connecting the contact-maker with the brace carrying the solcleringtube, whereby the two may be moved simultaneously substantially as specified.

3. The combination in an electric solderingiron, of the insulating-head, the crank-shaft to the upper end of which it is swiveled the circuit-making casing connected to the head by suitable tubes, the sleeves secured to an insulating-plate in the upper part of said casing and carrying spring-actuated contactwheels, the contact-ring secured in an insulating-plate in the lower part of the casing, upon which the contact-wheels are adapted to travel and conductors leading to the wheels, and contact-plates, wherebya continuous oil cuit is maintained as the crank-shaft is rotated, substantially as specified.
